ICE-CREAM Specicaton of Letters Patent No.

To all 'whom it may concern:

Be it known that I, E. I). ToRnEY, of J ersey City, in the county ofHudson and State of New Jersey, have invented a new and ImprovedIce-Cream Freezer; and I do hereby declare that the following is a full,clear, and exact description of the same, reference being had to theannexed drawings, making a part of this specification, in which- Figurel, represents a vertical central section of an ice cream freezerconstructed according to my invention. Fig. 2, is a horizontal sectionof the same.

Similar letters of reference indicate correspending parts in the twofigures.

To enable others skilled in the art to make and use my invention, I willproceed to describe it.

A, is a can made of tin, sheet metal, or other suitable material in acylindrical form, and its bottom B, is provided with a socket a, whichforms the step for the stem C, of the beater D, and the cover E, of thecan is strengthened in the center by a boss through which the stem C, ofthe beater passes freely, as clearly represented in Fig. l, and thesocket a, together with the boss b, form the bearings for the stem ofthe beater. The beater is constructed on one side of a series of slatsc, perfectly smooth and placed in the beater frame el, in a positionwhich is inclined from the outside toward the center, and the other sideof the beater contains a scraper E, which works up close enoughto thesides of the can to keep them free from ice but not so close as to causethe beater to bind, and I lind that a rigid scraper will all theyielding scrapers, as the forlner in no case gives a chance to the creamto adhere to the sides of the can to form ice there.

The form of my scraper is clearly represented in Fig. 2, and it may beconstructed of wood or metal, but I prefer making it of wood, as a.wooden scraper does not injure the sides of the can when it comes incontact with them, and yet it performs its duty, viz: to peep the sidesclear of ice just as perfectly as a metal scraper could do it.

The bottom of the can is provided with legs or projections c, which fitover a cross bar F, which is rigidly attached to the bottom of thebarrel or pail G, which surrounds the can and this cross bar is providedin its center with a cavity f, which receives that FREEZER.

part of the bottom B, of the can which forms the socket a, for the stemC, of the beater.

By this means the cross bar F, serves to keep the can in the middle ofthe barrel, and at the same time the legs e, as they come in contactwith the sides of the cross bar F, prevent the can from turning, andalso serve to keep the can erect when the beater is operated. The stemC, of the beater passes freely through an opening L, in the cover H, ofthe barrel or pail, which is placed on loosely and-which requires noextra fastenings as the stem of the beater is guided in such a manner inthe can A, that the cover H, is relieved of all pressure; and the stelnC, extends beyond the cover H, and it ends in a square part to which thecrank I, is attached.

The operation is as follows:-The cream is poured in the can A, and itscover E, is placed on firmly and the can is placed in the barrel G, thesocket a, being inserted into the cavity f, in the cross bar F, and twoof the legs c, being placed close up to the sides of this cross bar, asclearly represented in Fig. l. The freezing mixture is now packed intothe barrel G, around the can A, in the usual manner. The cover H, may ormay not be placed on the barrel G, but it is desirable to have it on, asthe action of the' freezing mixture on the cream in the can is moreuniform, and quicker if the cover is on than when the same is off andthe beater is now rotated by means of the crank I.

As fast as the cream is thrown upon the sides of the can, it is cut offor removed by the action of the scraper E, and then beaten and liftedand again spread over the surface of the can, to be further cooled. Thegreater the ext-ent of freezing surface over which the cream can bespread, and the more thorough the beating which it receives, the quickerwill the operation be concluded and the better will be the quality ofthe icecream.

The slats (c), by being inclined, lift the cream upward and so spread itover the entire surface of the can, and at the same time thoroughly beatit. The dasher E, by being rigid, thoroughly removes the cream from thesides of the can, and thus rapidly presents a` clean and thereforeactive refrigerating surface for the reception of the cream.

For economy of time and ice, it is of the first importance that thescraper should thoroughl clean the sides of the can. If a coating ocream be left thereon, it is comparatively as difficult to freeze thecream as it is to raise steam in a boiler Whose interior surface iscoated With scale.7

I do not claim the employment of a beater having straight slats; nor doI claim the use of an'elastic or yielding scraper. But

Having described my invention, I Claim as new and desire to secure byLetters Patent:
